Yesterday, we released several samples and mini-games to help you get started using the Windows Phone Developer Tools CTP (which includes the XNA Game Studio 4.0 CTP) to create games for Windows Phone 7 Series.  Here is some additional information about the samples and where you can download them:

• Reach graphics demo – this is the demo that Shawn Hargreaves used in his talks at GDC and MIX to show the 5 five built-in effect types provided by the XNA Framework 4.0 on Windows Phone (BasicEffect, DualTextureEffect, AlphaTestEffect, SkinnedEffect, and EnvironmentMapEffect).
  
  
• Snow Shovel mini-game – a simple Windows Phone game that shows how draw 2D sprites using SpriteBatch and handles player input using the accelerometer. You will not be able to use accelerometer input in the Windows Phone 7 Series emulator in the Windows Phone Developer Tools CTP however.
  
  
• Primitives sample – an updated version of an existing sample that works with the XNA Game Studio 4.0 CTP and demonstrates how to create a reusable class to draw 2D primitives (points, lines and triangles) on the screen.  The source code for the 4.0 version of this sample is available at this link.
  
  
• Primitives3D sample - an updated version of an existing sample that works with the XNA Game Studio 4.0 CTP and demonstrates how to create a reusable class to draw 3D primitives (cubes, spheres, cylinders, torus and teapots) on the screen.  The source code for the 4.0 version of this sample is available at this link.
